Patient's question:
Sperm and egg implantation after several daysDoctor's answer:
Implantation is the process by which the early embryo of a placental mammal fuses with the uterine wall of the mother, establishing a structural connection between mother and child to facilitate material exchange. This physiological phenomenon is very complex; although there are some common patterns, individual differences are also very large. Generally speaking, in the early stages of fertilized egg implantation, it is likely that these symptoms may exist: a slight, dull ache and sour sensation in the lower abdomen, a sense of fullness and tenderness in the nipples, and sometimes even a feeling of fatigue similar to a cold.
